Abstract: In order to solve the disadvantages of the traditional rail transit test stand controller, such as unable to be customized, difficult protection of intellectual property rights, single interface, unable to synchronously sample and intelligent operation and maintenance, this paper designed a general controller system based on ZYNQ (ARM+FPGA) as the main processor and CPLD and MCU as the slave processors. Among them, ARM processor is used for Ethernet communication, wireless communication, big data storage, control logic and control algorithm implementation, and at the same time fast communication with FPGA through internal AXI bus interface.FPGA mainly uses the self-developed high-speed serial communication mode (SSB bus) and the slave processor CPLD to communicate. CPLD completes the requirement of high-speed parallel data acquisition by controlling multi-chip AD7606. ARM also communicates with MCU through CAN communication interface, realizing the expansion and control of low-speed multi-interface acquisition. The practical application of the controller shows that the controller can be flexibly configured as a test controller for each core control system of rail transit, and the verification of each function, performance and algorithm required by each core control system is completed, and the product performance is reliable.
